| 摘 要： | A mixed-ligand copper(Ⅱ） complex[Cu2(phen)2(HL^1)2]-(ClO4)2(1) was synthesized.X-ray analyses reveal that 1 has a bis(μ2-phenoxo)-bridged dicopper(Ⅱ） structure.2D hydrogen-bonded network is formed utilizing the N-H,O-H and C-H groups of the (HL^1) ligands (H2L^1=N-(2-hydroxybenzyl)ethanolamine),the C-H groups of the phenanthrolines and the perchlorate anions.Variable temperature magnetic properties of 1 have shown comparatively weak antiferromagnetic interactions with respect to the bridge angles, which have been ascribed to the unfavorable overlaps of the magnetic orbitals fo the highly distorted copper coordination polyhedra and the pyramidal distortions at the phenoxo oxygen atoms.

| Abstract: | A mixed‐ligand copper (II) complex [Cu2 (phen)2 (HL1)2] ‐ (ClO4)2 (I) was synthesized. X‐ray analyses reveal that 1 has a bis (μ2‐phenoxo)‐bridged dicopper (II) structure. 2D hydrogen‐bonded network is formed utilizing the N‐H, O‐H and C‐H groups of the (HL1)? ligands (H2L1 = N‐(2‐hydroxybenzyl) ethanolamine), the C‐H groups of the phenanthrolines and the perchlorate anions. Variable temperature magnetic properties of 1 have shown comparatively weak antiferromagnetic interactions with respect to the bridge angles, which have been ascribed to the unfavorable overlaps of the magnetic orbitals for the highly distorted copper coordination polyhedra and the pyramidal distortions at the phenoxo oxygen atoms. |
